Spreads words out evenly in the text block so that each line ends in the same spot on the right side of the text block. The last line in a paragraph (too short to fill the entire line) will be set to 'left'.

This software can't currently handle those alignments with any markup tags. As written the software is in a loop calculating x position of each word, one word at a time from left to right. But in the case of aligns 'right' and 'center' we don't know the position of the first word until we know the x positions of ALL words. We need a smarter handler for this scenario. See t/30-demo.t.
